ANSI Screw Engineering Slide Chart Selector[7355]

I have my TAD Metric-English universal reference calculator since 1985. I'm looking that it's available only for ANSI.... I have love this product since I but it. I take care of it like water in the desert. But it's showing signs of age, some numbers are beginning to fade. Is it possible to get the metric-english back.
